-
Basic Fighter Maneuver - Training designed to apply aircraft handling skills to gain proficiency in recognizing and solving range, closure, aspect, angle off, and turning room problems in relation to another aircraft to either attain a position from which weapons may be employed or deny the adversary a position from which weapons may be launched or defeat weapons employed by an adversary. Examples are the high speed yo-yo, quarter plane maneuver, Immelmann turn, barrel roll. BFM training builds appreciation of pursuit geometry, cutoff, radial G, rolling maneuvers and energy management.
